RUNNING-LIGHT SYSTEM AND ,B OARD.

Application filed August 22, 1928 Serial No. 658,799'ir.

To all whom it may concern:

Be it known that I, JOHN W. HAYWOOD, a citizen of the United States, andresident of the borough of Bronx, county of Bronx, city and State of NewYork, have. invented certain new and useful Improvements in Runnin-Light Systems and Boards, of which t e following is the specification.

The invention relates to running light systems for ships. The inventioncomprises an improved system wherein each of the ships signals containstwo lamps, as is not uncommon, and in which the circuit branches for thetwo lamps are controlled jointly by a relay and a' switch, in suchmanner that the switch will complete a path through the coil of therelay and one or other of the branches, according to its position, whilethe armature of the relay is, adapted automatically to complete a paththrough the switch, remaining in position, to the other branch, uponfailure of the lamp then in circuit with the coil. Upon throw ing theswitch the lamp automatically lighted by the armature remains burning,because, while the path established by the armature is broken, a path isrestored through the coil and the branch containing this lamp. The relayfor each of the running lights controls an indicator on the boardcorresponding to that light; and in addi-,

tion there is a common alarm the circuit of A which is branched to eachof the relays,so

that upon failure of a lamp of any one or more of. the lights this alarmis sounded, calling attention to the condition shown by the indicators.Preferably there is a dual indicator on theboard for each running light,comprising a lam and a luminous indicator card, or legen -bearingmember, the latter being read-able in the dark even if the correspondingindicator lamp should burn out.

In the' accompanying drawings forming a arthereof:."

g. 1 is a front elevation of a four-panel board embodying the invention,with one of the panels removed;

Fig.3 is across-section through the frame and one of the panels, theintermediate and major portion of the panel being broken awayfor economyoispace; and

' Fig. 4 is a fragmentary side elevation of a relay. 1

Similar reference numerals indicate like parts in all the figures wherethey appear.

The board has a main panel 1 and any desired number of panels 1,connected, respectively, with different running lights. The panels 1 areduplicates of each other, and the board illustrated contains three ofthem, though thenumber may be varied.

The main panel bears a main double-pole single-throw switch 2, fuses 3,3 and abuzz er 4. Each. of the panels 1 has a triple-pole double-throwswitch 5, a fuse 6, a relay 7 and a lamp 8. The wiring will now beexplained.

The characters 9, 9 designate the conductors of the supply line,connected with the blades of the double-pole switch 2. Each of therunning lights or signals of the ship contains two lamps 10, 10, onlyone of which receives current at a time. It will be sufficient toconsider the main circuit, one

of thevsignals and its circuits and devices.

With the main switch 2 closed and the switch 5 of the adjacent panel 1in the left-hand position seen in Fig. 1, the circuits may be traced asfollows: from line wire 9 and one of the poles of switch 2, to conductor11 on the panel 1, said conductor having fuse "3 therein, to a main wire12 on the frame 13 of the board, to conductor-1.4; on the panel 1, tothe pivot terminal 15 of 1 one ofthe blades of the switch 5, thence toswitch contact 18 at the left, thence by conductor 21 to correspondingcontact 18" at the right, to conductor22, to connection 23 connectedwith the armature 24: of the relay v7, by conductor 25 to the coil 26 ofthis relay, through the coil to conductor 27 to the mlddle pivotterminal 16 of the switch, through the middle blade to the contact 19 atthe left, by conductor 28 on the panel 1 and external conductor 291tothe lamp 10 of the signal, by conductor 30 back. to the panel 1'9, byconductor 31 on the panel, containing fuse 6, to conductor 32 on theframe, to main conductor 33 on-the frame, back to panel 1, to. conductor34 thereon, to conductor 35* containing fuse 3, to the other blade ofthe switch 2, to the othersupply line 9. If the lamp 10 burns out, thecircuit through the coil 26 of the relay is broken and its armature 24drops, forming electrical connection with two contacts 36 and 37.Thereby circuits are established as follows. Current still flows as justdescribed up to the connection 23 at the armature of the relay. Thencethe current passes through the armature to contact 36, thence byconductor 38 to the pivot terminal 17 of the switch 5, through the upperblade of this switch to contact at the left, by conductor 39 to middlecontact 19 at the right, by conductor 40 on the panel and externalconductor 41 tothe lamp 10 thence back by conductor to the panel, andfrom this point on as with the clrcuit prev ously traced. Lamp 10 isthus automatically lighted upon the failure of lamp 10.

'Another circuit branches from the switch terminal 17 through conductor42 to indicator lamp 8 on the panel 1*, which is thus lighted, toconductor 43, to conductors 32 and, 33 on the frame, and thence back tothe supply line as previously traced. In addition to this indicationcontrolled by the armature 24 of the relay, the dropping of the armatureitself gives an' indication bymoving the word Burning away from a windowin the relay case and bringing the word Out into View, these legendsbeing printed in luminous paint on a suitable card 8 carried byarmature. Thus, a double indication is given, and in case the lamp 8should be out of order, the armature, or electromagnetic device,controlling its circuit, will still afl'ord a signal which is readilydiscernible in the dark. I

A. third circuit can be traced from the contact 37, by way of-conductor44 on the panel 1 to a main conductor 45 on the frame, to conductor 46on the panel 1, to

the buzzer 4, which is energized, by conductor 47 to the conductor andthence backto the supply line. This alarm or sigand inserts a fresh lampin placeof the denal is given, therefore, when a lamp of any of theships running lights goes out.

Warned by the alarm the person whose duty it is goes to the board and bythe indication on one of the panels 1 is advised as to which of therunning lights contains a burned-out lamp. He then throws the switch 5of thispanel to the other position; that is to say if he finds it at theleft he throws it to the right, while if at the right he throws it tothe left. Either position is a normal position. He then goes to thelight ment of the switch 5 away from contact 20, but another circuit isclosed which includes this lamp and the relay coil 26. This circuitincludes conductor 14, pivot terminal 15, contact 18, conductors 22,conductor 25, coil 26, conductor 27, pivot terminal 16, contact 19conductors 40. 41, lamp 10 conductors 30, 31, and so on back to line.The coil 26 being enerized, its armature is automatically raise thusremoving the Out sign from View and restoring Burning, and breaking thecircuitthrough the buzzer 4, which ceases to sound.

, If now lamp 1O burns, out, (lamp 10 having been replaced), the circuitthrough the coil 26 is broken as before, the armature drops, and acircuit is completed from the contact 36, through conductor 38, pivotterminal 17, the upper blade of the switch 5, contact 2O at the right,conductor 39" to contact 19, through conductors 28, 29 to lamp 10, backby conductor 30, to conductor 31 on the panel, and so on back to line.

When the-switch 5 is again thrown to the left, *the circuit is againestablished through the coil 26 and the branch containing the lamp- 10,the armature 24 is restored to its normal condition and the indicatorsandv alarm are also restored to normal condition.

The board itself will now be described. The top and bottom members ofthe frame have internal back flanges or ledges 50. In these are mountedforwardly projecting studs 51, three at top and two at bottom in thecase of the panel 1, and three at top and three at bottom in the case ofeach of the panels 1*. These studs are clamped to the flanges by collars52 at the front and nuts 53 in recesses at the back. The collars '52 maybe fast on the studs or abut against shoulders thereon. Wire terminalbrackets 54 are clamped between the collars 52 and the flanges 50, inelectrical connection with the. studs. The wires which run along theframe are secured to the terminal brackets by binding screws 55. Theprecise construction and arrangement of the studs and terminals may,however, be varied, though that illustrated is thought to be especiallyadvantageous. I

The terminals 56 of the wiring on the panels preferably compriseplatesor strips secured to the backs of the panels by screws 57. Theseterminals, are located on the board with reference to the correspondingterminals on the frame. In the present construction holes 58 are formedthrough the panelsand their terminals 56, in positions to take over thestuds. This done, insulated nuts 59 are screwed on to the projectingthreaded ends of the studs, and the panels are thereby clamped to theframe, and their terminals at the same time electricall connected with"the terminals on the e,

- cuits comprising branches for two lamps, a

without fuss or difliculty. Spring washers 60 may be interposed betweenthe terminals 56 and the collars 52.
